Abstract
Intraoperative frozen section (IFS) is used with the intention to improve functional and oncological outcomes for patients undergoing radical prostatectomy (RP). High resource requirements of IFS techniques such as NeuroSAFE may preclude widespread adoption, even if there are benefits to patients. Recent advances in fresh-tissue microscopic digital imaging technologies may offer an attractive alternative, and there is a growing body of evidence regarding these technologies. In this narrative review, we discuss some of the familiar limitations of IFS and compare these to the attractive counterpoints of modern digital imaging technologies such as the speed and ease of image generation, the locality of equipment within (or near) the operating room, the ability to maintain tissue integrity, and digital transfer of images. Confocal laser microscopy (CLM) is the modality most frequently reported in the literature for margin assessment during RP. We discuss several imitations and obstacles to widespread dissemination of digital imaging technologies. Among these, we consider how the 'en-face' margin perspective will challenge urologists and pathologists to understand afresh the meaning of positive margin significance. As a part of this, discussions on how to describe, categorize, react to, and evaluate these technologies are needed to improve patient outcomes. Limitations of this review include its narrative structure and that the evidence base in this field is relatively immature but developing at pace.

Abstract
OBJECTIVE To present the results of the first series of patients treated with robot-assisted radical prostatectomy (RARP) with the use of the Versius® Surgical System (CMR Surgical Ltd., Cambridge, UK). RARP has demonstrated better perioperative outcomes compared to open RP. However, RARP remains limited by platform availability and cost-effectiveness issues. The increasing competition from new robotic surgical platforms may further drive utilisation of the robotic approach. PATIENTS AND METHODS Data were collected prospectively for our first 18 consecutive patients with localised prostate cancer who underwent RARP at our centre over a 3-month period. We recorded parameters, including patient demographics and perioperative outcomes. We also report our optimised set-up with regard to trocar placement, bedside unit placement, and overall composition of the operating room for this procedure. Describing the incremental modifications carried out to achieve reductions in set-up and operating times to optimise utilisation of the Versius system. RESULTS The median (interquartile range [IQR]) set-up time was 8.5 (7-10) min. The median (IQR) console time was 201 (170-242) min. The median (IQR) operative time was 213 (186-266) min. The median (IQR) total surgery time was 226 (201-277) min. Bilateral pelvic lymphadenectomy median (IQR) time was 19 (17-20) min. There were no complications and/or limitations related to the use of the Versius system including need for conversion. There were no relevant intra- or postoperative complications at the 1-month follow-up related to the use of the Versius system. Patients were discharged after a median (IQR) of 4 (3.75-5) days, and the transurethral catheter was removed after a mean (range) of 8 (7-14) days. Continence at 2 months was achieved in 72.2% of the patients. CONCLUSIONS Performing RARP using the Versius system is feasible, safe, and easily reproducible. Our set-up enables a rapid docking approach and efficient completion of the surgery.

Tiruye T, O'Callaghan M, Ettridge K, Moretti K, Jay A, Higgs B, Santoro K, Kichenadasse G, Beckmann K. Clinical and functional outcomes for risk-appropriate treatments for prostate cancer. BJUI COMPASS 2024; 5:109-120. [PMID: 38179028 PMCID: PMC10764171 DOI: 10.1002/bco2.288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/14/2023] [Accepted: 08/15/2023] [Indexed: 01/06/2024] Open
Abstract
Objectives To describe real-world clinical and functional outcomes in an Australian cohort of men with localised prostate cancer according to treatment type and risk category. Subjects and methods Men diagnosed from 2008 to 2018 who were enrolled in South Australian Prostate Cancer Clinical Outcomes Collaborative registry-a multi-institutional prospective clinical registry-were studied. The main outcome measures were overall survival, cancer-specific survival, decline in functional outcomes, biochemical recurrence and transition to active treatment following active surveillance. Multivariable adjusted models were applied to estimate outcomes. Results Of the 8513 eligible men, majority of men (46%) underwent radical prostatectomy (RP) followed by external beam radiation therapy with or without androgen deprivation therapy (EBRT +/- ADT) in 22% of the cohort. Five-year overall survival was above 91%, and 5-year prostate cancer-specific survival was above 97% in the low- and intermediate-risk categories across all treatments. Five-year prostate cancer-specific survival in the active surveillance group was 100%. About 37% of men with high-risk disease treated with RP and 17% of men treated with EBRT +/- ADT experienced biochemical recurrence within 5 years of treatment. Of men on active surveillance, 15% of those with low risk and 20% with intermediate risk converted to active treatment within 2 years. The decline in urinary continence and sexual function 12 months after treatment was greatest among men who underwent RP while the decline in bowel function was greatest for men who received EBRT +/- ADT. Conclusion This contemporary real-world evidence on risk-appropriate treatment outcomes helps inform treatment decision-making for clinicians and patients.
